General Comments. ( Brief data summary and scan listing )
C band phase-referencing global experiment, observed on 6th June 2006. Line mode pass. Data rate was 256 Mbps (2 X 8 MHz subbands, dual polarization, two-bit sampling). The target source was 'ARP220', '1613+341'and '1516+193' were also observed as calibrators.
17 stations participated. See experiment feedback for recording problems.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.93 . ERI* = 0.93 . (VLBA stations 0.95, NT=1, ON=1, TR=1, WB=0.6, EF=0.95, MC=1, JB=0.99)

TSYS against time
Comments.
WB is better than GD021B, but all EVN stations show small 'jumps' in Tsys

Telescope sensitivities from the a priori TSYS and Gain curves (the square of this number gives the antenna noise (SEFD) in Jy - the smaller the better).
